In chemical graph theory, a graph is designed by considering atoms as vertices and edges as bonds between atoms of a particular molecule. A graph is a mathematical model used to predict the topology of a given system. A topological index is a numeric quantity from the structure of a graph which is invariant under auto morphisms of the graph under consideration. Also the edge version of Zagreb index of graphs is introduced based on the end-vertex degrees of edges of their line graphs. In this paper, we computed the Zagreb and edge Zagreb indices for Polyamine Chain.
